SPINDLE AND DEVICE FOR L U BRICATING THE SAME.

SPECIFICATION forming part of Letters Patent No. 256,288, dated April 11, 1882,

' Application filed March 18, 1881. (No model.)

To all whom it may concern:

Beit known thatI, CHARLES H.0HAP1IAN, of Shirley, in the county of Middlesex and State of Massachusetts, have invented certain Improvementsin Spindles,of which thefollowingisa specification.

This invention relates to the class of spindles shown in Letters Patent of the United States granted to me October 19, 1880, No. 233,474, said spindle having an oil-reservoir, a grooved standard rising from the reservoir, and a livespindle supported on the standard.

The bearing-surfaces of the standard and spindle shown in said patent are lubricated by oil raised from the reservoir through the grooved standard by atmospheric pressure, superinduced by the upward movement. of the spindle, caused by the act of doffing the bobbin. My present invention has for its object to enable oil to be forced or injected upwardly to lubricate said bearing-surfaces by the downward movement of the spindle when the same is retnrningto place after being raised in the act of doffing the bobbin.

The invention also has for its object to provide improved means for preventing the oil in the reservoir from working upward on the walls thereof and escaping over the top.

To these ends my invention consists, first, in

the hereinafter-described construction of the oil-reservoir and the spindle,whereby the latter is enabled when moved downwardly to inject oil upwardly through the grooved standard.

The invention alsoconsists in the provision of a spiral flange on the inner surface of the oil-reservoir to prevent the upward workin g of the oil over the topof said reservoir, all of which Iwill now proceed to describe.

.Of the accompanyingdrawings, forming part of this specification, Figure 1 represents a vertical section of a spindle embodying my invention. Figure 2 represents asimilar section, .with the spindle raised.

In these figures the same letters indicate the same parts.

In the drawings, a represents the oil-reservoir, adapted to be secured to the rail of a spinning-machine.

i) represents the standard, rigidly affixed to the bottom of the oil-reservoir, or to the rail,

' r and provided with a longitudinal groove. 0, as

in my above-mentioned patent.

The oil-reservoir is composed of a contracted portion, 1, concentric with the standard I), a small enlargement, 2, below the portion 1 atthe bottom of 5 the reservoir, and a large enlargement or chamber 3, above the portion 1, constituting the chief portion of the reservoir.

drepresents the spindle, composed ofa tubular portion inclosing the standard I), and a tip 60 to hold the bobbin. The lower end of the tubular portion of the spindle has anontwardlyprojecting annular flange, e, which is adapted to fit somewhat closely in the portion 1 of the oil-reservoir, and constitute a piston when in said portion. a

The spindle is provided with a foot or hearing, j, which rests on the upper end of the standard I and above the foot f, with an airchamber, 9, communicating with the interior of the tubular portion of the spindle.

The operation is as follows: When the spindle is in its normal position its flange e-is in the lower enlarged portion, 2, of the oil-reservoir, as shown in Fig. 1, and when the spindle is raised by the act of doifing the bobbin the flange 0 passes upwardly through the contracted portion 1 and into the portion 3 of the oil-reservoir. \Vhen the standard is lowered to its normal position the flange e, acting as a piston in the portion 1, forces or injects the oil below it into the groove 0, and thereby lubricates the bearing surfaces of the spindle. The air between the spindle and shell is forced into the air-chamber g by the injected oil, so that the oil 8 5 is not prevented by' such air from reaching the surfaces to be lubricated, the chamber g being of such size that the air contained in it admits of sufficient compression to enable the oil to reach said surfaces. o

The inner surface of the main portion 3 of the oil-reservoir is provided with a continuous spiral flange, i, the object of which is to prevent the oil in the reservoir from working upwardlyover the top of the reservoir. The flange 5 presents a continuous inclined surface, which causes any oil that may work upwardly on the walls of the reservoir to run back along said surface to the body of the oil inthe reservoir, the flow of oil alou g said inclined surface being '1 oo facilitated by the motion imparted to the oil by the rotation of the spindle.

I am aware that a bearing for a live-spindle has been scored or grooved spirally to force downward the excess of oil carried upward by the spindle when in motion, said bearing being in contact with the spindle. 'lhe flange, 2, however, is on the wall of an oil-reservoir, not in contact with the spindle. Hence it acts only to prevent the natural tendency of the oil in the reservoir to work upwardly on the walls thereof.

Having thus described my invention, 1 claim- 1. The combination,substantially as setforth, of agrooved standard, an oil-reservoir surrounding the base of the standard, and com.- posed of a contracted annular portion and enlarged portions above and below the same, a

gitudinally with relation to said standard, and provided at its lower end with a flange fitting closely in the contracted portion of the oil-reservoir, an air-space in the spindle above the standard, and a stop tolirnit the upward movement of the spindle on the standard.

2. The eombination,with the rotary spindle, of the oil-reservoir surrounding the base of said spindle, and provided with a spiral inwardly-projecting flange separated from the spindle, and adapted to prevent the oil from working upwardly on the walls of the reservoir, as set forth.

In testimony whereot'l have signed my name to this specification, in the presence of two subscribing witnesses, this 16th day of March, A.D. 1881.

CHARLES H. CHAPMAN.
